Patent JP-H07182686-A (JP)
Title: Optical mode converter and optical demultiplexer
Inventor: KITAGAWA TETSUO
IPC: G11B7/135
Filed: 1993-12-21
Abstract: PURPOSE:To obtain an optical mode converter for simply and effectively mode- converting a light with a simple structure and an optical demultiplexer using it. CONSTITUTION:A thickness T of a waveguide layer 2 is so decided that the value of a normalizing frequency V obtained from the thickness T falls in the range between a primary cut-off V1 and a secondary cut-off V2 (V1<V<V2). As a result, mode components of a guided light 6 have only a zero order and a primary order. The light 6 of the zero-order mode component is output as an emitted light 7a having a large emission angle, and the light 6 of the primary order mode component is output as an emitted light 7b having a small emission angle from a coupler 3B. Accordingly, the primary order mode light incident with a simple structure is efficiently converted into a zero-order mode light, and the zero-order mode light can be preserved as retained as the zero-order mode light.

IPC: B60B35/16
Filed: 1989-12-13
Abstract: PURPOSE:To eliminate hydraulic oil leak from a double acting hydraulic cylinder and prevent any accidental tread change by installing a double pilot check valve on the hydraulic oil supply port of the double acting hydraulic cylinder which expands and contracts an axle. CONSTITUTION:The hydraulic oil from a low pressure auxiliary hydraulic pump 8b is supplied to a double acting hydraulic cylinder 12 through a double acting change-over valve 20, a directional change-over valve 21 and a double pilot check valve 19. When the upper spool of the directional change-over valve 21 is pulled to the right and the spool of the double acting change-over valve 20 is pushed to the right, hydraulic oil is supplied to the contracting side oil chamber 16 of the left double acting hydraulic cylinder 12 to discharge hydraulic oil in an expanding side oil chamber 15. However, discharge of hydraulic oil in the expanding side chamber 15 is inhibited by the double pilot check valve 19. Consequently, supply side pressure rises and a discharge side check valve 22 opens, so that hydraulic oil in the expanding side oil chamber 15 is discharged, and a traveling body 13 moves in a contracting direction.

Title: Electricity saving circuit and electricity saving method for monitor
Inventor: YUN YEO SUNG
IPC: G06F1/32
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To reduce the electric power consumption of a monitor by automatically turning off a main power source of the monitor and/or a heater power source according to a plurality of electricity saving signals when a computer is not used for a specified time. SOLUTION: When a user does not use the computer, i.e., when horizontal and vertical synchronizing signals are not supplied to the monitor from a main body, the microcomputer 18 recognizes a electricity saving made. Namely, unless the horizontal and vertical synchronizing signal are detected for the specified time or longer from the computer, the microcomputer 18 judges a standby mode. Unless the horizontal and vertical synchronizing signals are not detected for the specified time or longer in succession thereto at the time of the stand by mode, the microcomputer 18 recognizes an off mode. At the time of the off mode, the microcomputer 18 output first and second DPM control signals which are both of low levels and, therefore, a switching section 16 shuts off the heater power source + B8 according to the first DPM control signal.  Then, the power-supply voltage is not supplied to a main power source control section 13 and the switching operation of the main control section 13 is not carried out.

IPC: G06F7/533
Filed: 1987-12-21
Abstract: PURPOSE:To improve the scale and action speed of a hardware multiplier by storing the result of the development of a coefficient according to the algorithm of a Booth into a ROM. CONSTITUTION:The result obtained by developing the contents of the coefficient ROM according to the secondary Booth algorithm is written into a coefficient ROM 101. Here, for the output of the coefficient ROM 101, a logic is not obtained, and a shifting/adding-subtracting logic 3 is directly controlled. Consequently, the coefficient ROM 101 is more redundant compared with the conventional ROM, while, a developing logic is not required. Thus, the scale and action time of the hardware multiplier are improved.

Title: Rotary head cylinder
Inventor: HINO MASAYUKI
IPC: G11B15/61
Filed: 1989-12-14
Abstract: PURPOSE:To stabilize signal transmission of a magnetic recording and reproducing head, and a magnetic tape by non-linearly increasing the air groove cross-sectional area per unit length in the direction of an axis formed on a rotary drum in addition to the area which comes over the rotary drum of the magnetic tape as it departs further away from a fixed drum. CONSTITUTION:For an air groove 5 formed on a rotary drum 1, the air groove cross-sectional area is not only increased monotonically taking into account the linear change of the area of a magnetic tape 7 which comes over the rotary drums 1, but the air groove cross-sectional area for each unit length in the axial direction is increased non-linearly taking into account the change of the tension of the magnetic tape 7. Then, the floating height of the magnetic tape 7 can be uniformized from the enter side part to the exit side part of a rotary head cylinder. Thus, the recording and reproducing by the magnetic recording and reproducing head can be stabilized.
